UG8HT-E3/45

The UG8HT-E3/45 is a single rectifier diode commonly used for applications requiring the conversion of alternating current (AC) to direct current (DC). As a unidirectional device where current flows in only one direction, the UG8HT-E3/45 is adept at rectifying AC to DC and can be used in a variety of applications.

Characteristics of UG8HT-E3/45

The UG8HT-E3/45 has several distinct characteristics. It is a single rectifier diode, meaning it contains one diode element with a single junction. It also has an 800-volt repetitive peak reverse voltage (VRRM), a 45-amp average forward current (IFAv) in continuous operation and a 0.95-max forward voltage drop (VFmax) in the forward direction. In addition, the UG8HT-E3/45 features a 2.2-nanosecond (ns) trr and a -65°C max junction temperature.

Application fields

The UG8HT-E3/45 is used in a variety of application fields such as AC-to-DC power conversion, DC link switching circuits, DC-to-AC power converters, AC-to-AC power converters, DC-to-DC power converters, AC motor speed control, DC motor speed control, DC motor control, UPS systems, welding machines, plasma cutters, uninterruptible power supplies (UPS), computer power supplies, and audio power amplifiers.

The UG8HT-E3/45 is well-suited to environments where shock and vibration might present a problem. In addition, its rectification efficiency is often praised for its ability to maintain low energy losses. Consequently, this rectifier diode is a great choice for applications where power conversion is essential.

Working Principle

When AC power is applied to the UG8HT-E3/45 in the form of a sine wave, the diode begins to conduct when the positive portion of the wave reaches the threshold voltage (VBR). As the diode conducts, it dumps the positive portion of the current into a capacitor and an inductor connected in series. The capacitor stores the positive charge, while the inductor helps to reduce high frequency noise.

Once the positive portion of the wave has been removed, the diode stops conducting and thevoltage reverses, dropping to the negative portion of the wave. At this point, the diode begins to conduct again. As the cycle repeats, the UG8HT-E3/45 works to continously rectify AC power to DC, which can be used in a variety of applications.

Conclusion

The UG8HT-E3/45 is a single rectifier diode, which can be used in a variety of applications to convert AC power to DC power. It is characterized by a 800-volt repetitive peak reverse voltage, a 45-amp average forward current in continuous operation, and a 0.95-max forward voltage drop. Its rectification efficiency and tolerance to shock and vibration make the UG8HT-E3/45 perfect for applications where AC-to-DC power conversion is necessary.
